solar storage

Adding batteries to our current solar plants will take our solar to the next
level by making it available after the sun goes down. Plus we’re building new
solar storage plants and standalone batteries across the state.

clean energy plays a big role in meeting Arizona’s energy needs today and tomorrow. Looking ahead to Arizona’s growing population and expanding economic activity, we continue supporting resources and technology to ensure our energy is cleaner, more reliable and affordable for all Arizonans.

Today, we serve customers with an energy mix that is already 50% clean.

APS currently has 10 large-scalesolar plants across Arizona.

The Palo Verde Generation Station provides 70% of Arizona's carbon-free energy and uses recycled wastewater to cool the plant.

shaping the future with clean energy

​​​Your energy is being generated in increasingly clean ways. The Palo Verde Nuclear Generating Station is already the largest source of carbon-free electricity in the nation. We are also transitioning from older coal units to more efficient natural-gas plants. More than two-thirds of the water we use to generate energy comes from reclaimed water sources. Moving forward, we will meet growing energy needs with zero- to low-emission resources to create a sustainable future for all of Arizona.

supporting those who have served

APS and ENERGY STAR Partners have come together to makeover a US Vets facility that is currently home to 135 veterans. The facility received energy efficiency upgrades– saving the US Vets organization $40,000 a year in energy costs; another example of our award winning commitment to helping our community be more energy efficient.​

APS and its customers are committed to a future where Arizona’s energy is increasingly cleaner. The projected growth of renewable energy, combined with other environmentally friendly efforts, is predicted to make the overall APS energy mix cleaner and more efficient.

We anticipate by 2029:

2x the amount of renewable energy

3x as much rooftop solar generation

3x as much savings from energy-efficiency measures

14% less carbon dioxide emissions per megawatt-hour of electricity generated

24% less water usage per megawatt-hour of electricity generated

driving arizona's solar leadership

​​​

Since 1954, we’ve advanced solar energy throughout the state. Our efforts continue today with programs like APS Solar Partner, an innovative study that brings rooftop solar to customers and supports the long-term growth of solar energy. We’ve also helped more than 300 schools go solar and introduced solar curriculum into the classroom. Today, we generate more solar energy than any utility outside California because we know solar has an integral role in Arizona’s energy future.

biogas - landfill

It’s hard to imagine that waste could provide a clean source of energy, but it’s a reality at landfills in Glendale and Surprise. When organic materials break down, they produce methane gas, which is used to fuel large combustion engines that generate power. We purchase nearly all the clean energy generated at these landfills and efficiently distribute it to customers across the state.

four corners

The recent closure of three coal-fired units at the Four Corners Power Plant, which we operate, will make our overall energy mix cleaner and more efficient for generations to come. Ending operation of the older units 1 – 3 will dramatically reduce our carbon footprint in the Four Corners region, while continuing operation of units 4 and 5 will keep high-quality jobs in the Navajo Nation and Farmington areas.

We anticipate that by 2029, our portfolio will produce 14% less carbon dioxide and use 24% less water per megawatt-hour of electricity generated than today, drastically reducing energy’s environmental impact in Arizona.

The proposed modernization of Ocotillo Power Plant in Tempe will create a cleaner-running, more-efficient plant that helps us meet growing customer demand in the metro Phoenix area. Five new natural gas combustion turbines will decrease the plant's overall water usage and emission rates, reduce the plant’s visibility from surrounding neighborhoods, and decrease noise conditions – all while maintaining the reliability our customers require.
